A wolf us chasing a rabbit.Graph the wolf's motion using the following data: 15 m\s at 0 s,10 m\s at 3 s,1 m\s at 4 s,and 0 m\s at 5 s.What does the graph tell you???

Math
Could someone explain how to graph the following problem? I don't quite understand what "Graph H for 0 ≤ t ≤ 3 and 300 ≤ H ≤ 340" is asking me to do... The National Oceanic and Atmospheric Administration (NOAA) has been measuring atmospher...

American History
true or false The Great Migration was a large-scale movement of hundreds of thousands of southern African Americans to Weswtern farms.

physics
exactly. This is all I was given. Possibly SumOf t = T(exp)*length* sin(theta) - W(hang) * length * sin(phi) - W(boom) * L(exp) * sin(phi) = 0 but im not sure.

physics
The torques acting on the crane boom can be computed about anaxis passing through the top of the boom. (this is the place wherethe spring scale and mass hanger connect to the boom) apply thesecond condition for equilibrium to the crane boom and derivethe resulting equation for...

physics
a clothes washer starts from rest and spins up with an angular accceleration of 10/rad/s^2. Determine the angle through which the washer has moved afer 6 seconds.

Math
this problem is modelling daylight hours using the form y = d+a sin[b(t-c)], btw

Math
How would I solve for t if y equals 720 minutes of daylight and t=the number of days in 2012 720 = 713.7+152.7 sin [(2pi/366)(t-80.75)]

trig
i think i figured out my mistake. it should be 720 = 713.7+152.7 sin [(2pi/366)(t-80.75)] this problem is modelling minutes of daylight in a town using the form y = d+a sin[b(t-c)]. let y equal 720 minutes of daylight and let t=the number of days in 2012

trig
How would I solve this problem for t? 720 = 11.895+2.545sin [2pi/366(t-80.5)]
